Extensions may add new commands, add options to existing commands, change the default behavior of commands, or implement hooks. To enable the "foo" extension, either shipped with Mercurial or in the Python search path, create an entry for it in your configuration file, like this: [extensions] foo = You may also specify the full path to an extension: [extensions] myfeature = ~/.hgext/myfeature.py See 'hg help config' for more information on configuration files. Extensions are not loaded by default for a variety of reasons: they can increase startup overhead; they may be meant for advanced usage only; they may provide potentially dangerous abilities (such as letting you destroy or modify history); they might not be ready for prime time; or they may alter some usual behaviors of stock Mercurial. It is thus up to the user to activate extensions as needed. To explicitly disable an extension enabled in a configuration file of broader scope, prepend its path with !: [extensions] # disabling extension bar residing in /path/to/extension/bar.py bar = !/path/to/extension/bar.py # ditto, but no path was supplied for extension baz baz = ! enabled extensions: children command to display child changesets (DEPRECATED) rebase command to move sets of revisions to a different ancestor disabled extensions: acl hooks for controlling repository access blackbox log repository events to a blackbox for debugging bugzilla hooks for integrating with the Bugzilla bug tracker censor erase file content at a given revision churn command to display statistics about repository history clonebundles advertise pre-generated bundles to seed clones closehead close arbitrary heads without checking them out first convert import revisions from foreign VCS repositories into Mercurial eol automatically manage newlines in repository files extdiff command to allow external programs to compare revisions factotum http authentication with factotum fastexport export repositories as git fast-import stream githelp try mapping git commands to Mercurial commands gpg commands to sign and verify changesets hgk browse the repository in a graphical way highlight syntax highlighting for hgweb (requires Pygments) histedit interactive history editing keyword expand keywords in tracked files largefiles track large binary files mq manage a stack of patches notify hooks for sending email push notifications patchbomb command to send changesets as (a series of) patch emails relink recreates hardlinks between repository clones schemes extend schemes with shortcuts to repository swarms share share a common history between several working directories transplant command to transplant changesets from another branch win32mbcs allow the use of MBCS paths with problematic encodings zeroconf discover and advertise repositories on the local network #endif Verify that deprecated extensions are included if --verbose: $ hg -v help extensions | grep children children command to display child changesets (DEPRECATED) Verify that extension keywords appear in help templates $ hg help --config extensions.transplant= templating|grep transplant > /dev/null Test short command list with verbose option $ hg -v help shortlist Mercurial Distributed SCM basic commands: abort abort an unfinished operation (EXPERIMENTAL) add add the specified files on the next commit annotate, blame show changeset information by line for each file clone make a copy of an existing repository commit, ci commit the specified files or all outstanding changes continue resumes an interrupted operation (EXPERIMENTAL) diff diff repository (or selected files) export dump the header and diffs for one or more changesets forget forget the specified files on the next commit init create a new repository in the given directory log, history show revision history of entire repository or files merge merge another revision into working directory pull pull changes from the specified source push push changes to the specified destination remove, rm remove the specified files on the next commit serve start stand-alone webserver status, st show changed files in the working directory summary, sum summarize working directory state update, up, checkout, co update working directory (or switch revisions) global options ([+] can be repeated): -R --repository REPO repository root directory or name of overlay bundle file --cwd DIR change working directory -y --noninteractive do not prompt, automatically pick the first choice for all prompts -q --quiet suppress output -v --verbose enable additional output --color TYPE when to colorize (boolean, always, auto, never, or debug) --config CONFIG [+] set/override config option (use 'section.name=value') --debug enable debugging output --debugger start debugger --encoding ENCODE set the charset encoding (default: ascii) --encodingmode MODE set the charset encoding mode (default: strict) --traceback always print a traceback on exception --time time how long the command takes --profile print command execution profile --version output version information and exit -h --help display help and exit --hidden consider hidden changesets --pager TYPE when to paginate (boolean, always, auto, or never) (default: auto) (use 'hg help' for the full list of commands) $ hg add -h hg add [OPTION]...

This will perform an extensive check of the repository's integrity, validating the hashes and checksums of each entry in the changelog, manifest, and tracked files, as well as the integrity of their crosslinks and indices. Please see https://mercurial-scm.org/wiki/RepositoryCorruption for more information about recovery from corruption of the repository. Returns 0 on success, 1 if errors are encountered. options: (some details hidden, use --verbose to show complete help) $ hg help diff hg diff [OPTION]... ([-c REV] | [--from REV1] [--to REV2]) [FILE]... diff repository (or selected files) Show differences between revisions for the specified files. Differences between files are shown using the unified diff format. Note: 'hg diff' may generate unexpected results for merges, as it will default to comparing against the working directory's first parent changeset if no revisions are specified. By default, the working directory files are compared to its first parent. To see the differences from another revision, use --from. To see the difference to another revision, use --to. For example, 'hg diff --from .^' will show the differences from the working copy's grandparent to the working copy, 'hg diff --to .' will show the diff from the working copy to its parent (i.e. the reverse of the default), and 'hg diff --from 1.0 --to 1.2' will show the diff between those two revisions. Alternatively you can specify -c/--change with a revision to see the changes in that changeset relative to its first parent (i.e. 'hg diff -c 42' is equivalent to 'hg diff --from 42^ --to 42') Without the -a/--text option, diff will avoid generating diffs of files it detects as binary. With -a, diff will generate a diff anyway, probably with undesirable results. Use the -g/--git option to generate diffs in the git extended diff format. For more information, read 'hg help diffs'. Returns 0 on success. options ([+] can be repeated): --from REV1 revision to diff from --to REV2 revision to diff to -c --change REV change made by revision -a --text treat all files as text -g --git use git extended diff format --binary generate binary diffs in git mode (default) --nodates omit dates from diff headers --noprefix omit a/ and b/ prefixes from filenames -p --show-function show which function each change is in --reverse produce a diff that undoes the changes -w --ignore-all-space ignore white space when comparing lines -b --ignore-space-change ignore changes in the amount of white space -B --ignore-blank-lines ignore changes whose lines are all blank -Z --ignore-space-at-eol ignore changes in whitespace at EOL -U --unified NUM number of lines of context to show --stat output diffstat-style summary of changes --root DIR produce diffs relative to subdirectory -I --include PATTERN [+] include names matching the given patterns -X --exclude PATTERN [+] exclude names matching the given patterns -S --subrepos recurse into subrepositories (some details hidden, use --verbose to show complete help) $ hg help status hg status [OPTION]... [FILE]... aliases: st show changed files in the working directory Show status of files in the repository. If names are given, only files that match are shown. Files that are clean or ignored or the source of a copy/move operation, are not listed unless -c/--clean, -i/--ignored, -C/--copies or -A/--all are given. Unless options described with "show only ..." are given, the options -mardu are used. Option -q/--quiet hides untracked (unknown and ignored) files unless explicitly requested with -u/--unknown or -i/--ignored. Note: 'hg status' may appear to disagree with diff if permissions have changed or a merge has occurred. The standard diff format does not report permission changes and diff only reports changes relative to one merge parent. If one revision is given, it is used as the base revision. If two revisions are given, the differences between them are shown. The --change option can also be used as a shortcut to list the changed files of a revision from its first parent. The codes used to show the status of files are: M = modified A = added R = removed C = clean ! = missing (deleted by non-hg command, but still tracked) ? = not tracked I = ignored = origin of the previous file (with --copies) Returns 0 on success. options ([+] can be repeated): -A --all show status of all files -m --modified show only modified files -a --added show only added files -r --removed show only removed files -d --deleted show only missing files -c --clean show only files without changes -u --unknown show only unknown (not tracked) files -i --ignored show only ignored files -n --no-status hide status prefix -C --copies show source of copied files -0 --print0 end filenames with NUL, for use with xargs --rev REV [+] show difference from revision --change REV list the changed files of a revision -I --include PATTERN [+] include names matching the given patterns -X --exclude PATTERN [+] exclude names matching the given patterns -S --subrepos recurse into subrepositories -T --template TEMPLATE display with template (some details hidden, use --verbose to show complete help) $ hg -q help status hg status [OPTION]...

There are 4 versions of changegroups: "1", "2", "3" and "4". From a high- level, versions "1" and "2" are almost exactly the same, with the only difference being an additional item in the *delta header*. Version "3" adds support for storage flags in the *delta header* and optionally exchanging treemanifests (enabled by setting an option on the "changegroup" part in the bundle2). Version "4" adds support for exchanging sidedata (additional revision metadata not part of the digest). Changegroups when not exchanging treemanifests consist of 3 logical segments: +---------------------------------+ | | | | | changeset | manifest | filelogs | | | | | | | | | +---------------------------------+ When exchanging treemanifests, there are 4 logical segments: +-------------------------------------------------+ | | | | | | changeset | root | treemanifests | filelogs | | | manifest | | | | | | | | +-------------------------------------------------+ The principle building block of each segment is a *chunk*. A *chunk* is a framed piece of data: +---------------------------------------+ | | | | length | data | | (4 bytes) | (<length - 4> bytes) | | | | +---------------------------------------+ All integers are big-endian signed integers. Each chunk starts with a 32-bit integer indicating the length of the entire chunk (including the length field itself). There is a special case chunk that has a value of 0 for the length ("0x00000000"). We call this an *empty chunk*. Delta Groups ============ A *delta group* expresses the content of a revlog as a series of deltas, or patches against previous revisions. Delta groups consist of 0 or more *chunks* followed by the *empty chunk* to signal the end of the delta group: +------------------------------------------------------------------------+ | | | | | | | chunk0 length | chunk0 data | chunk1 length | chunk1 data | 0x0 | | (4 bytes) | (various) | (4 bytes) | (various) | (4 bytes) | | | | | | | +------------------------------------------------------------------------+ Each *chunk*'s data consists of the following: +---------------------------------------+ | | | | delta header | delta data | | (various by version) | (various) | | | | +---------------------------------------+ The *delta data* is a series of *delta*s that describe a diff from an existing entry (either that the recipient already has, or previously specified in the bundle/changegroup). The *delta header* is different between versions "1", "2", "3" and "4" of the changegroup format. Version 1 (headerlen=80): +------------------------------------------------------+ | | | | | | node | p1 node | p2 node | link node | | (20 bytes) | (20 bytes) | (20 bytes) | (20 bytes) | | | | | | +------------------------------------------------------+ Version 2 (headerlen=100): +------------------------------------------------------------------+ | | | | | | | node | p1 node | p2 node | base node | link node | | (20 bytes) | (20 bytes) | (20 bytes) | (20 bytes) | (20 bytes) | | | | | | | +------------------------------------------------------------------+ Version 3 (headerlen=102): +------------------------------------------------------------------------------+ | | | | | | | | node | p1 node | p2 node | base node | link node | flags | | (20 bytes) | (20 bytes) | (20 bytes) | (20 bytes) | (20 bytes) | (2 bytes) | | | | | | | | +------------------------------------------------------------------------------+ Version 4 (headerlen=103): +------------------------------------------------------------------------------+----------+ | | | | | | | | | node | p1 node | p2 node | base node | link node | flags | pflags | | (20 bytes) | (20 bytes) | (20 bytes) | (20 bytes) | (20 bytes) | (2 bytes) | (1 byte) | | | | | | | | | +------------------------------------------------------------------------------+----------+ The *delta data* consists of "chunklen - 4 - headerlen" bytes, which contain a series of *delta*s, densely packed (no separators). These deltas describe a diff from an existing entry (either that the recipient already has, or previously specified in the bundle/changegroup). The format is described more fully in "hg help internals.bdiff", but briefly: +---------------------------------------------------------------+ | | | | | | start offset | end offset | new length | content | | (4 bytes) | (4 bytes) | (4 bytes) | (<new length> bytes) | | | | | | +---------------------------------------------------------------+ Please note that the length field in the delta data does *not* include itself. In version 1, the delta is always applied against the previous node from the changegroup or the first parent if this is the first entry in the changegroup. In version 2 and up, the delta base node is encoded in the entry in the changegroup. This allows the delta to be expressed against any parent, which can result in smaller deltas and more efficient encoding of data. The *flags* field holds bitwise flags affecting the processing of revision data. The following flags are defined: 32768 Censored revision. The revision's fulltext has been replaced by censor metadata. May only occur on file revisions. 16384 Ellipsis revision. Revision hash does not match data (likely due to rewritten parents). 8192 Externally stored. The revision fulltext contains "key:value" "\n" delimited metadata defining an object stored elsewhere. Used by the LFS extension. 4096 Contains copy information. This revision changes files in a way that could affect copy tracing. This does *not* affect changegroup handling, but is relevant for other parts of Mercurial. For historical reasons, the integer values are identical to revlog version 1 per-revision storage flags and correspond to bits being set in this 2-byte field. Bits were allocated starting from the most-significant bit, hence the reverse ordering and allocation of these flags. The *pflags* (protocol flags) field holds bitwise flags affecting the protocol itself. They are first in the header since they may affect the handling of the rest of the fields in a future version. They are defined as such: 1 indicates whether to read a chunk of sidedata (of variable length) right after the revision flags. Changeset Segment ================= The *changeset segment* consists of a single *delta group* holding changelog data. The *empty chunk* at the end of the *delta group* denotes the boundary to the *manifest segment*. Manifest Segment ================ The *manifest segment* consists of a single *delta group* holding manifest data. If treemanifests are in use, it contains only the manifest for the root directory of the repository. Otherwise, it contains the entire manifest data. The *empty chunk* at the end of the *delta group* denotes the boundary to the next segment (either the *treemanifests segment* or the *filelogs segment*, depending on version and the request options). Treemanifests Segment --------------------- The *treemanifests segment* only exists in changegroup version "3" and "4", and only if the 'treemanifest' param is part of the bundle2 changegroup part (it is not possible to use changegroup version 3 or 4 outside of bundle2). Aside from the filenames in the *treemanifests segment* containing a trailing "/" character, it behaves identically to the *filelogs segment* (see below). The final sub-segment is followed by an *empty chunk* (logically, a sub-segment with filename size 0). This denotes the boundary to the *filelogs segment*. Filelogs Segment ================ The *filelogs segment* consists of multiple sub-segments, each corresponding to an individual file whose data is being described: +--------------------------------------------------+ | | | | | | | filelog0 | filelog1 | filelog2 | ... | 0x0 | | | | | | (4 bytes) | | | | | | | +--------------------------------------------------+ The final filelog sub-segment is followed by an *empty chunk* (logically, a sub-segment with filename size 0). This denotes the end of the segment and of the overall changegroup. Each filelog sub-segment consists of the following: +------------------------------------------------------+ | | | | | filename length | filename | delta group | | (4 bytes) | (<length - 4> bytes) | (various) | | | | | +------------------------------------------------------+ That is, a *chunk* consisting of the filename (not terminated or padded) followed by N chunks constituting the *delta group* for this file. The *empty chunk* at the end of each *delta group* denotes the boundary to the next filelog sub-segment. non-existent subtopics print an error $ hg help internals.foo abort: no such help topic: internals.foo (try 'hg help --keyword foo') [10] test advanced, deprecated and experimental options are hidden in command help $ hg help debugoptADV hg debugoptADV (no help text available) options: (some details hidden, use --verbose to show complete help) $ hg help debugoptDEP hg debugoptDEP (no help text available) options: (some details hidden, use --verbose to show complete help) $ hg help debugoptEXP hg debugoptEXP (no help text available) options: (some details hidden, use --verbose to show complete help) test advanced, deprecated and experimental options are shown with -v $ hg help -v debugoptADV | grep aopt --aopt option is (ADVANCED) $ hg help -v debugoptDEP | grep dopt --dopt option is (DEPRECATED) $ hg help -v debugoptEXP | grep eopt --eopt option is (EXPERIMENTAL) #if gettext test deprecated option is hidden with translation with untranslated description (use many globy for not failing on changed transaction) $ LANGUAGE=sv hg help debugoptDEP hg debugoptDEP (*) (glob) options: (some details hidden, use --verbose to show complete help) #endif Test commands that collide with topics (issue4240) $ hg config -hq hg config [-u] [NAME]... show combined config settings from all hgrc files $ hg showconfig -hq hg config [-u] [NAME]... show combined config settings from all hgrc files Test a help topic $ hg help dates Date Formats """""""""""" Some commands allow the user to specify a date, e.g.: - backout, commit, import, tag: Specify the commit date. - log, revert, update: Select revision(s) by date.

This graph can be visualized by graphical tools such as 'hg log --graph'. In Mercurial, the DAG is limited by the requirement for children to have at most two parents. $ hg help hgrc.paths "paths" ------- Assigns symbolic names and behavior to repositories. Options are symbolic names defining the URL or directory that is the location of the repository. Example: [paths] my_server = https://example.com/my_repo local_path = /home/me/repo These symbolic names can be used from the command line. To pull from "my_server": 'hg pull my_server'. To push to "local_path": 'hg push local_path'. You can check 'hg help urls' for details about valid URLs. Options containing colons (":") denote sub-options that can influence behavior for that specific path. Example: [paths] my_server = https://example.com/my_path my_server:pushurl = ssh://example.com/my_path Paths using the 'path://otherpath' scheme will inherit the sub-options value from the path they point to. The following sub-options can be defined: "multi-urls" A boolean option. When enabled the value of the '[paths]' entry will be parsed as a list and the alias will resolve to multiple destination. If some of the list entry use the 'path://' syntax, the suboption will be inherited individually. "pushurl" The URL to use for push operations. If not defined, the location defined by the path's main entry is used. "pushrev" A revset defining which revisions to push by default. When 'hg push' is executed without a "-r" argument, the revset defined by this sub-option is evaluated to determine what to push. For example, a value of "." will push the working directory's revision by default. Revsets specifying bookmarks will not result in the bookmark being pushed. The following special named paths exist: "default" The URL or directory to use when no source or remote is specified. 'hg clone' will automatically define this path to the location the repository was cloned from. "default-push" (deprecated) The URL or directory for the default 'hg push' location. "default:pushurl" should be used instead. $ hg help glossary.mcguffin abort: help section not found: glossary.mcguffin [10] $ hg help glossary.mc.guffin abort: help section not found: glossary.mc.guffin [10] $ hg help template.files files List of strings.

Test section lookup by translated message str.lower() instead of encoding.lower(str) on translated message might make message meaningless, because some encoding uses 0x41(A) - 0x5a(Z) as the second or later byte of multi-byte character. For example, "\x8bL\x98^" (translation of "record" in ja_JP.cp932) contains 0x4c (L). str.lower() replaces 0x4c(L) by 0x6c(l) and this replacement makes message meaningless.

A merge tool combines two different versions of a file into a merged file. Merge tools are given the two files and the greatest common ancestor of the two file versions, so they can determine the changes made on both branches. Merge tools are used both for 'hg resolve', 'hg merge', 'hg update', 'hg backout' and in several extensions. Usually, the merge tool tries to automatically reconcile the files by combining all non-overlapping changes that occurred separately in the two different evolutions of the same initial base file. Furthermore, some interactive merge programs make it easier to manually resolve conflicting merges, either in a graphical way, or by inserting some conflict markers. Mercurial does not include any interactive merge programs but relies on external tools for that. Available merge tools ===================== External merge tools and their properties are configured in the merge- tools configuration section - see hgrc(5) - but they can often just be named by their executable. A merge tool is generally usable if its executable can be found on the system and if it can handle the merge. The executable is found if it is an absolute or relative executable path or the name of an application in the executable search path. The tool is assumed to be able to handle the merge if it can handle symlinks if the file is a symlink, if it can handle binary files if the file is binary, and if a GUI is available if the tool requires a GUI. There are some internal merge tools which can be used. The internal merge tools are: ":dump" Creates three versions of the files to merge, containing the contents of local, other and base. These files can then be used to perform a merge manually. If the file to be merged is named "a.txt", these files will accordingly be named "a.txt.local", "a.txt.other" and "a.txt.base" and they will be placed in the same directory as "a.txt". This implies premerge. Therefore, files aren't dumped, if premerge runs successfully. Use :forcedump to forcibly write files out. (actual capabilities: binary, symlink) ":fail" Rather than attempting to merge files that were modified on both branches, it marks them as unresolved. The resolve command must be used to resolve these conflicts. (actual capabilities: binary, symlink) ":forcedump" Creates three versions of the files as same as :dump, but omits premerge. (actual capabilities: binary, symlink) ":local" Uses the local 'p1()' version of files as the merged version. (actual capabilities: binary, symlink) ":merge" Uses the internal non-interactive simple merge algorithm for merging files. It will fail if there are any conflicts and leave markers in the partially merged file. Markers will have two sections, one for each side of merge. ":merge-local" Like :merge, but resolve all conflicts non-interactively in favor of the local 'p1()' changes. ":merge-other" Like :merge, but resolve all conflicts non-interactively in favor of the other 'p2()' changes. ":merge3" Uses the internal non-interactive simple merge algorithm for merging files. It will fail if there are any conflicts and leave markers in the partially merged file. Marker will have three sections, one from each side of the merge and one for the base content. ":mergediff" Uses the internal non-interactive simple merge algorithm for merging files. It will fail if there are any conflicts and leave markers in the partially merged file. The marker will have two sections, one with the content from one side of the merge, and one with a diff from the base content to the content on the other side. (experimental) ":other" Uses the other 'p2()' version of files as the merged version. (actual capabilities: binary, symlink) ":prompt" Asks the user which of the local 'p1()' or the other 'p2()' version to keep as the merged version. (actual capabilities: binary, symlink) ":tagmerge" Uses the internal tag merge algorithm (experimental). ":union" Uses the internal non-interactive simple merge algorithm for merging files. It will use both left and right sides for conflict regions. No markers are inserted. Internal tools are always available and do not require a GUI but will by default not handle symlinks or binary files. See next section for detail about "actual capabilities" described above. Choosing a merge tool ===================== Mercurial uses these rules when deciding which merge tool to use: 1. If a tool has been specified with the --tool option to merge or resolve, it is used. If it is the name of a tool in the merge-tools configuration, its configuration is used. Otherwise the specified tool must be executable by the shell. 2. If the "HGMERGE" environment variable is present, its value is used and must be executable by the shell. 3. If the filename of the file to be merged matches any of the patterns in the merge-patterns configuration section, the first usable merge tool corresponding to a matching pattern is used. 4. If ui.merge is set it will be considered next. If the value is not the name of a configured tool, the specified value is used and must be executable by the shell. Otherwise the named tool is used if it is usable. 5. If any usable merge tools are present in the merge-tools configuration section, the one with the highest priority is used. 6. If a program named "hgmerge" can be found on the system, it is used - but it will by default not be used for symlinks and binary files. 7. If the file to be merged is not binary and is not a symlink, then internal ":merge" is used. 8. Otherwise, ":prompt" is used. For historical reason, Mercurial treats merge tools as below while examining rules above. step specified via binary symlink ---------------------------------- 1. --tool o/o o/o 2. HGMERGE o/o o/o 3. merge-patterns o/o(*) x/?(*) 4. ui.merge x/?(*) x/?(*) Each capability column indicates Mercurial behavior for internal/external merge tools at examining each rule. - "o": "assume that a tool has capability" - "x": "assume that a tool does not have capability" - "?": "check actual capability of a tool" If "merge.strict-capability-check" configuration is true, Mercurial checks capabilities of merge tools strictly in (*) cases above (= each capability column becomes "?/?"). It is false by default for backward compatibility. Note: After selecting a merge program, Mercurial will by default attempt to merge the files using a simple merge algorithm first. Only if it doesn't succeed because of conflicting changes will Mercurial actually execute the merge program. Whether to use the simple merge algorithm first can be controlled by the premerge setting of the merge tool. Premerge is enabled by default unless the file is binary or a symlink. See the merge-tools and ui sections of hgrc(5) for details on the configuration of merge tools. Compression engines listed in `hg help bundlespec` $ hg help bundlespec | grep gzip "v1" bundles can only use the "gzip", "bzip2", and "none" compression An algorithm that produces smaller bundles than "gzip".

treemanifest data, and filelogs. </p> <p> There are 4 versions of changegroups: "1", "2", "3" and "4". From a high-level, versions "1" and "2" are almost exactly the same, with the only difference being an additional item in the *delta header*. Version "3" adds support for storage flags in the *delta header* and optionally exchanging treemanifests (enabled by setting an option on the "changegroup" part in the bundle2). Version "4" adds support for exchanging sidedata (additional revision metadata not part of the digest). </p> <p> Changegroups when not exchanging treemanifests consist of 3 logical segments: </p> <pre> +---------------------------------+ | | | | | changeset | manifest | filelogs | | | | | | | | | +---------------------------------+ </pre> <p> When exchanging treemanifests, there are 4 logical segments: </p> <pre> +-------------------------------------------------+ | | | | | | changeset | root | treemanifests | filelogs | | | manifest | | | | | | | | +-------------------------------------------------+ </pre> <p> The principle building block of each segment is a *chunk*. A *chunk* is a framed piece of data: </p> <pre> +---------------------------------------+ | | | | length | data | | (4 bytes) | (<length - 4> bytes) | | | | +---------------------------------------+ </pre> <p> All integers are big-endian signed integers. Each chunk starts with a 32-bit integer indicating the length of the entire chunk (including the length field itself). </p> <p> There is a special case chunk that has a value of 0 for the length ("0x00000000"). We call this an *empty chunk*. </p> <h2>Delta Groups</h2> <p> A *delta group* expresses the content of a revlog as a series of deltas, or patches against previous revisions. </p> <p> Delta groups consist of 0 or more *chunks* followed by the *empty chunk* to signal the end of the delta group: </p> <pre> +------------------------------------------------------------------------+ | | | | | | | chunk0 length | chunk0 data | chunk1 length | chunk1 data | 0x0 | | (4 bytes) | (various) | (4 bytes) | (various) | (4 bytes) | | | | | | | +------------------------------------------------------------------------+ </pre> <p> Each *chunk*'s data consists of the following: </p> <pre> +---------------------------------------+ | | | | delta header | delta data | | (various by version) | (various) | | | | +---------------------------------------+ </pre> <p> The *delta data* is a series of *delta*s that describe a diff from an existing entry (either that the recipient already has, or previously specified in the bundle/changegroup). </p> <p> The *delta header* is different between versions "1", "2", "3" and "4" of the changegroup format. </p> <p> Version 1 (headerlen=80): </p> <pre> +------------------------------------------------------+ | | | | | | node | p1 node | p2 node | link node | | (20 bytes) | (20 bytes) | (20 bytes) | (20 bytes) | | | | | | +------------------------------------------------------+ </pre> <p> Version 2 (headerlen=100): </p> <pre> +------------------------------------------------------------------+ | | | | | | | node | p1 node | p2 node | base node | link node | | (20 bytes) | (20 bytes) | (20 bytes) | (20 bytes) | (20 bytes) | | | | | | | +------------------------------------------------------------------+ </pre> <p> Version 3 (headerlen=102): </p> <pre> +------------------------------------------------------------------------------+ | | | | | | | | node | p1 node | p2 node | base node | link node | flags | | (20 bytes) | (20 bytes) | (20 bytes) | (20 bytes) | (20 bytes) | (2 bytes) | | | | | | | | +------------------------------------------------------------------------------+ </pre> <p> Version 4 (headerlen=103): </p> <pre> +------------------------------------------------------------------------------+----------+ | | | | | | | | | node | p1 node | p2 node | base node | link node | flags | pflags | | (20 bytes) | (20 bytes) | (20 bytes) | (20 bytes) | (20 bytes) | (2 bytes) | (1 byte) | | | | | | | | | +------------------------------------------------------------------------------+----------+ </pre> <p> The *delta data* consists of "chunklen - 4 - headerlen" bytes, which contain a series of *delta*s, densely packed (no separators). These deltas describe a diff from an existing entry (either that the recipient already has, or previously specified in the bundle/changegroup). The format is described more fully in "hg help internals.bdiff", but briefly: </p> <pre> +---------------------------------------------------------------+ | | | | | | start offset | end offset | new length | content | | (4 bytes) | (4 bytes) | (4 bytes) | (<new length> bytes) | | | | | | +---------------------------------------------------------------+ </pre> <p> Please note that the length field in the delta data does *not* include itself. </p> <p> In version 1, the delta is always applied against the previous node from the changegroup or the first parent if this is the first entry in the changegroup. </p> <p> In version 2 and up, the delta base node is encoded in the entry in the changegroup. This allows the delta to be expressed against any parent, which can result in smaller deltas and more efficient encoding of data. </p> <p> The *flags* field holds bitwise flags affecting the processing of revision data. The following flags are defined: </p> <dl> <dt>32768 <dd>Censored revision. The revision's fulltext has been replaced by censor metadata. May only occur on file revisions. <dt>16384 <dd>Ellipsis revision. Revision hash does not match data (likely due to rewritten parents). <dt>8192 <dd>Externally stored. The revision fulltext contains "key:value" "\n" delimited metadata defining an object stored elsewhere. Used by the LFS extension. <dt>4096 <dd>Contains copy information. This revision changes files in a way that could affect copy tracing. This does *not* affect changegroup handling, but is relevant for other parts of Mercurial. </dl> <p> For historical reasons, the integer values are identical to revlog version 1 per-revision storage flags and correspond to bits being set in this 2-byte field. Bits were allocated starting from the most-significant bit, hence the reverse ordering and allocation of these flags. </p> <p> The *pflags* (protocol flags) field holds bitwise flags affecting the protocol itself. They are first in the header since they may affect the handling of the rest of the fields in a future version. They are defined as such: </p> <dl> <dt>1 indicates whether to read a chunk of sidedata (of variable length) right <dd>after the revision flags. </dl> <h2>Changeset Segment</h2> <p> The *changeset segment* consists of a single *delta group* holding changelog data. The *empty chunk* at the end of the *delta group* denotes the boundary to the *manifest segment*. </p> <h2>Manifest Segment</h2> <p> The *manifest segment* consists of a single *delta group* holding manifest data. If treemanifests are in use, it contains only the manifest for the root directory of the repository. Otherwise, it contains the entire manifest data. The *empty chunk* at the end of the *delta group* denotes the boundary to the next segment (either the *treemanifests segment* or the *filelogs segment*, depending on version and the request options). </p> <h3>Treemanifests Segment</h3> <p> The *treemanifests segment* only exists in changegroup version "3" and "4", and only if the 'treemanifest' param is part of the bundle2 changegroup part (it is not possible to use changegroup version 3 or 4 outside of bundle2). Aside from the filenames in the *treemanifests segment* containing a trailing "/" character, it behaves identically to the *filelogs segment* (see below). The final sub-segment is followed by an *empty chunk* (logically, a sub-segment with filename size 0). This denotes the boundary to the *filelogs segment*. </p> <h2>Filelogs Segment</h2> <p> The *filelogs segment* consists of multiple sub-segments, each corresponding to an individual file whose data is being described: </p> <pre> +--------------------------------------------------+ | | | | | | | filelog0 | filelog1 | filelog2 | ... | 0x0 | | | | | | (4 bytes) | | | | | | | +--------------------------------------------------+ </pre> <p> The final filelog sub-segment is followed by an *empty chunk* (logically, a sub-segment with filename size 0). This denotes the end of the segment and of the overall changegroup. </p> <p> Each filelog sub-segment consists of the following: </p> <pre> +------------------------------------------------------+ | | | | | filename length | filename | delta group | | (4 bytes) | (<length - 4> bytes) | (various) | | | | | +------------------------------------------------------+ </pre> <p> That is, a *chunk* consisting of the filename (not terminated or padded) followed by N chunks constituting the *delta group* for this file. The *empty chunk* at the end of each *delta group* denotes the boundary to the next filelog sub-segment. </p> </div> </div> </div> </body> </html> $ get-with-headers.py 127.0.0.1:$HGPORT "help/unknowntopic" 404 Not Found <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en-US"> <head> <link rel="icon" href="/static/hgicon.png" type="image/png" /> <meta name="robots" content="index, nofollow" /> <link rel="stylesheet" href="/static/style-paper.css" type="text/css" /> <script type="text/javascript" src="/static/mercurial.js"></script> <title>test: error</title> </head> <body> <div class="container"> <div class="menu"> <div class="logo"> <a href="https://mercurial-scm.org/"> <img src="/static/hglogo.png" width=75 height=90 border=0 alt="mercurial" /></a> </div> <ul> <li><a href="/shortlog">log</a></li> <li><a href="/graph">graph</a></li> <li><a href="/tags">tags</a></li> <li><a href="/bookmarks">bookmarks</a></li> <li><a href="/branches">branches</a></li> </ul> <ul> <li><a href="/help">help</a></li> </ul> </div> <div class="main"> <h2 class="breadcrumb"><a href="/">Mercurial</a> </h2> <h3>error</h3> <form class="search" action="/log"> <p><input name="rev" id="search1" type="text" size="30" value="" /></p> <div id="hint">Find changesets by keywords (author, files, the commit message), revision number or hash, or <a href="/help/revsets">revset expression</a>.</div> </form> <div class="description"> <p> An error occurred while processing your request: </p> <p> Not Found </p> </div> </div> </div> </body> </html> [1] $ killdaemons.py #endif
